Alcohol fermentation conditions for the production of Chinese quince wine were investigated. Ethanol was produced maximally when 5% Saccharomyces cerevisiae was added to Chinese quince juices and fermented at 25 oC for 10 days. Physiological functionalities of the Chinese quince wines were determined and compared with those of Chinese quince liquors made by soaking of Chinese quince in a mixture of commercial soju and 10% sugar for 30 days and
60 days. Angiotensin-converting enzyme inhibitory activity and fibrinolytic activity of the Chinese quince wine were 36.7% and 24.0 U, respectively. Tyrosinase inhibitory activity and nitrite scavenging activity of the Chinese quince liquors were 96.7% and 52.7%, respectively and it were similar to those of the Chinese quince liquor made from soaking of 60 days. Chinese quince wine was showed strong antibacterial activities against Staphylococcus aureus (8.5 mm of clear zone) and Klebsiella pneumonia(4.0 mm of clear zone).

생리 기능성을 가진 고부가가치의 모과 술을 개발하기 위하여 먼저 최적 발효조건을 검토한 결과 모과 파쇄액(20obrix)에 Saccharomyces cerevisiae를 5% 접종하여 25℃에서 10일간 발효시켰을 때 에탄올이 가장 많이 생성(10.6%) 되었다. 모과발효주의 생리기능성을 조사한 결과 ACE 저해활성과 혈전용해활성은 각각 36.7%와 24.0 U이었고 tyrosinase 저해활성과 아질산염 제거 활성은 각각 96.7%와 52.7%을 보여 모과 60일 침출추와 유사하였다. 모과 발효주의 기관지 질환에 관여하는 S. aureus, K. pneumonia에 대한 항균활성(투명환)은 각각 8.5 mm과 4.0 mm로 비교적 강하였다.
